CHARLES WV. ATKESON, OF HENDERSON, KENTUCKY.

Specification forming part of Letters Patent No. 17.545, dated June 16,1 57.

To all whom it may concern.-

'Be it known that 1, CHARLES XV. ATKESON, of Henderson, in the county ofHenderson and State of Kentucky, have invented a new and ImprovedEvaporating and Steam Generating Apparatus or Boiler, by the use ofwhich I am enabled to speedily and economically reduce salt-water to thestate at which it must be run off into granulating-vats, and also at thesame time produce a sufficient quantity of steam in said apparatus to beconducted therefrom into heating-pipes in the aforesaid vats to completethe granulating process therein as fast as the strong brine is conductedinto them from the said evaporating apparatus; and I do hereby declarethat the following is a full and exact description thereof.

In the accompanying drawings, Figure 1 is a vertical section cut throughthe center of the aforesaid apparatus, and Fig. 2 is a section in theline 1 y of Fig. 1.

Similar letters indicate the same parts in both figures.

A is a furnace, constructed in any suitable and proper manner. Bis awater-tight chimney rising from said furnace and passing through thecentral portion of an inclosingboiler, G, which has a closedenlargement, D, at its upper extremity Series of transverse tubes (1. a,arranged in tiers one abovethe other, pass through the said chimney Band open freely into the boiler G,while the connectingjoints betweensaid tubes and the sides of the chimney are made watertight. It willtherefore be perceived that the said series of tubes to a add veryconsiderably to the capacity of the boiler C,at the same time that theyadd greatly to the efiicient heating-surface acted upon by the productsof combustion as they ascend from the furnace. The cover of theenlargement D at the head of the boiler 0 should be closed steam-tightaround the chimney The salt-water may be admitted into the boiler 0either at top or bottom through a close-jointed pipe. The enlargement Dat the top of the boiler facilitates the evaporat ing process byfurnishing an enlarged surface, from which the steam may freely rise andpass off into the heating-tubes in the granulatingvats. The saidenlargement also serves to prevent aviolent ebullition and foaming ofthe salt-water within theboiler. The salt water should rise a shortdistance into the enlargement D at the top of the boiler. The

enlargement D of the boiler should be 0011- nected by suitable pipeswith series of heatingpipes in a suitable number of broad and shallowgranulating-vats ot' the usual proportions. The bottom of the boilershould be connected by a stop-cock closed eductioirpipe with the saidgranulating-vats. After the brine with in the boiler has beensufficiently concentrated, it should be conducted into thegrauulatingvats,which are heated by the steam generated within saidboiler, and its place be supplied with salt-water as rapidly as the saidcolleen trated brine is allowed to run offinto the said granulatingvats. The concentrated brine should be allowed to pass off into thegranu lating-vats as rapidly as the process of granu lation takes placewithin said vats.

It will be perceived that the series of horizontal tubes to a in myevaporating apparatus, while they add vastly to the heating-surlhce andproduce a free circulation of the brine throughout the boiler, do notproduce violentagitatiou therein, nor are the currents sulli cientlyrapid to cause at'oaming aet ion within the boiler, whiclrassuredlywould be the case provided the said tubes were arranged in verticalpositions.

In my apparatus l effect cxaetl y what is desired in the process ofconcentrating salt-waterviz., a very rapid eva mratien without injuriousagitation of the brine within the boiler, and all with the greatesteconomy of space, fuel, and labor.

I am aware thata series of horizontal tubes have been combined with theline of a vertical cylindrical steam-boiler, and therefore I do notclaim said arrangement as my invention; but

\V hat I do claim,and desire to secure by Letters Patent, is

Combining a series of horizontal heatingtubes with a vertical line orchimney, when said line or chimney is combined with an inclosingvertical casing which has an enlargement at its upper end entirely abovethe up permost of the said heating-tubes, substantially as herein setforth.

The above specification of my new and improved evaporatingapparatussigned and witnessed this 24th day of February, 1857.

O. \V. ATKESON.
